NONSKIDJDING nnvrcn m. nuromonru s.

, Application filed March 23, 1925. Serial No. 17,705.

To all whom it may concern:

- Be it known that we, JOHN VVILLLAM ADKINS and ERNST EMIL GRABNER, CliilZQllS' of the United States, residing at The Dalles, in the county of W'asco and State of Oregon, have invented certain new and useful' Improvements in N onskidding Devices for Automobiles, of which the following is a specification.

This invention relates to a non-skidding device for automobiles, and particularly to a construction adapted to apply sand or other material in advance of the wheels thereof to secure the propertraction upon the road bed which will prevent either skidding or slipping of the wheels.

In devices of this character practical difficulty has been experienced insecuring a proper feeding of the sand to the delivery spout so as to assure the application thereof .in the event of emergency, and it has also vided' an improved pivotal mounting for the delivery valve and'spout, andalso a novel form of" sand box having pressure means to efiecta constant feed of the material therein toward the delivery opening in the box which when the spout is in position to apply the sand communicates with the valve member carried by said spout.

The invention has for an object to pro-- vide a novel and improved construction of sand box provided with a valve plate havin a-eurved'seat adapted to receive a cylindrical delivery valve provided with a discharge spout and also supporting caps for the ends of said valve rigidly mounted upon said plate.

A further object of the-invention is to provide a construction of delivery valve and spout supported at its ends by enclosing.

cap members carrying retracting springs which normally maintain the spoutin inoperative position, together with operating means extending from the steering wheel of the vehicle for shifting said spout into operative position relative to the wheels of the vehicle. Another object of the invention is to provide 'an improved construction of sand box communicating withfthe delivfenv box and spout and provlded with a tensioned feed member which causes the material in the boxto be constantly fed toward the delivery opening therein.

Other and further objects and advan-- tages of the invention willbe hereinafterset forth and the novel features thereof -de fined by the appended claims.

In the accompanying drawings Figure 1 is a side elevation of an automobile, with partsbroken away;

Figure 7 is a detail perspective of-one valve supporting cap; and

Figure8 is a similar view 'of the retaining clip for said cap.

The invention may be applied in any desired position upon the vehicle but for the purpose of illustration has been show n supported beneath the running board thereofv as being a very convenient and desirable location to effectively apply the sand or other material directly in advance of a traction wheel of the vehicle. In this application of the invention the numeral 10 indisize or configuratiom'for instance rectangu' lar as shown, and supported beneath the running board at the rear thereof by means of a U-s haped frame 16 which is provided with side flanges 17 adapted to receive and support-the flanges 18 at the upper portion of the sandbox. This sand is provided with a delivery opening 19 and hasdisposed' therein a telescopic feeding member 20 which is-movablelongitudinally of. the box and relative to the discharge opening 19. This follower or feeder 20 is normally un'- the tension 6r a coil spring '21 disposed between the rear wall 22' of the follower and the end 23 of the-box.- In filling the box with sand it is desirable to withdraw the follower so that the ,box may becom- Q pletely filled, and this is accomplished. bymeans of a rod 24 extending outwardly from the .box and the withdrawal of this rod so tensions the spring that when released it exerts a constant pressure 11 on the body of the sand within the. box, forcing it to- .ward the, delivery opening. Unless such ery valve and spout a bearing plate is secured to the bottom of the sand box by suitable fastening devices extending through the apertures in the flange 31 thereof. The central longitudinal portionof this plate is provided with a curved recess 32 having an aperture 33 which communicates with the opening 19 from the-sand box and at each end of this valve seat 32 concave bearings 34 are provided. A cylindrical valve 35 is disposed within .the seat 32 and formed with an inlet opening 36 in its circumference which is adapted to register with the open ing 38 of the plate when the, spout 3'r' is in depressed position for operative purposes as indicated by dotted lines in Figure 3. This spoutcommunicates with the valve by means of a tapering portion 38 and the opposite ends of the valve are closed by heads Surrounding these ends are supporting caps 40* which seat in the concave recesses 34 of the bearing plate and are retained against movement therein by means of a U-shaped clip 41 which is formed with a projection 42 adapted to seat in an aperture of the cap at its lower portion and retain the same against any rotary movement within the clip. The cap is also provided with a circumferential groove 43 within which the legs of the clip are adapted to lie. These legs are se cured in position by passing through apertured lugs 4-1 upon the bearing plate so that whensecuredin position by'the nuts 28 securely retain the cylindrical valve in position and form a bearing for the outer surf. face thereof.

In order to permit the removal and appli cation of the valve and caps as a unit a pivoting rod 45 extendsfthrough the oppog site caps andalso theend walls 39 ofthe valve. and those of the cap is utilized to contain a restoring springwhich normally holds the valve and spout in "inoperative position.

The space between these end walls Such a spring is shown at 46 where it is coiled about'the pivot rod 45' and has one 3 end 47 securedin the caphead and its op-posite end 48 valve. I

The delivery valve and spout is normally seated in the end wall 39 of the 3 held in elevated position as shown by full lines in Figure 3, and for the purpose of depressing the same into operative position for the delivery of the sand or other granular material directly in-advance of the traction wheel a crank shaft'50 is provided and has a lifter arm 51 operating within a slide loop 52 upon thes'pout member 37. The crank shaft is also provided with .an arm 53 from which a connecting rod 54 extends forward to the lower end of-the steering post last the machine where it'is connected by an arm 55 to the operating rod 56 mounted upon said steering post and-provided with a hanw dle 57 preferably disposed in convenient relation to the steering wheel. "While one or the sand boxes-may be used if desired, still ill) in general application th'ey'are appliedfat opposite sides of the machine and the rock shaft 50 extended across to, secure asimultaneous and joint operation thereof.

ln the-operation of the invention it will be seen that upon operation of the control handle by the driver the spout'is lowered, into a. delivery position adjacent the ground and applies the sand or other material upon the road bed directly in advance of the wheel'so that it is not wasted, and the immediate traction result desired is secured. When this spout is actuated into operative position a continuous flow of sand will be.

maintained as it feeds through thecylim drical valve and the pressure means within the sand box continues to advance the sand to position for such feeding. This is of practical importance in the case of icy streets where it is important to use the sand for a material distance, and means must be provided to prevent'clogging of the sand in the box which would prevent a propercontinuous feed thereof. The location of the sandbox beneath the running board protects it against moisture and when the parts are in inoperative position the box is efi'ectually closed either against the escape of material therefrom or the entrance of moisture 'which would dampen and pack the saline. This construction of the cylindrical delivery valve provides for its 'free pivoting within the caps and the looationjherein of the retracting springs which are thus protected from injury and rendered efieo tive at all times.

l/Vhile the specific construction of the invention has been shown and descgibed, still it is not confined thereto as changes and alterations therein may be made without departing from the spirit thereof as definedby the appended claims.
